Inertia Drive

Good for him. Is there a video that we can watch?

And do you know if he's tried it with different pendulum lengths, without changing the oscillation frequency of the drive?

(Sorry, I just can't crawl through that forum...I'll go blind, I know it.)

Here´s a system that apparently generates thrust using an asymetric microwave resonance cavity:

Shawyer's "EM" drive will soon, I hope, be tested in the definitive environment--outer space.
Smarter people than I have looked at Shawyer's maths and they think there are rather large errors.
I personally don't believe all experimental artifacts have been excluded.
What would be the effect of a tiny pinhole in the container, or an ion wind from some wiring or component at relatively high potential?
I just don't know, but since his math is suspect and the device appears to violate CofM, I'd put money on it being an error of some kind.

Not sure this will help, but i remember watching a tube video about 2 years ago tagged "lost technology" with alot a bits,  showing some guy and his device in a very large pool in the late 70's, patent applied, government dismissed, but the video looked like it worked pretty damn good to me. I just spent an hour tryn to find the vid on the tube to no avail.

Hi,

just have read about the Inertial Propulsion Device from Mr. Walden.
I have downloaded the patent file. But there are so many patent files out there.
What did Mr. Walden said about his device? Has he made a prototype yet?
